Pete,

You are going through what I went through with my 4x5 Linhof. A pure ground
glass is gritty and needs a fresnel lens to make it bright enough to use.
Focusing wide angle lenses was always a problem when using swings & tilts
because you have to focus, not only in the center of the screen, but at the
outside edges. Almost impossible with a fresnel lens (or bright screen). I
found a product, made in Holland, called the BOSSSCREEN. It's two very thin
pieces of glass with a very very thin layer of wax in between. It is
absolutely creamy smooth. No grit. And a pure joy to focus upon. Bright
from corner to corner. A savior! It's imported by Bromwell Marketing (412)
321-4118. You most likely would have to go to the manufacturer, which I
believe is:

Van Doornen Innovision, Stabilix B.V., Den Haag

What I wrote above, I copied off of the box, so you may need a little help
from our LUG European friends to actually track down these people. Or call
Mr. Bromwell, he is a very nice guy.
